    Isolating a single variable is often very difficult. There are obviously many interdependent variables in play and, to make matters more complicated, multiple, marginally functional causes can stack minor defects together to create big issues. This is especially true with older, worn machines (which is part of what makes preventive maintenance so important). We'll never know the cause(s) of your particular problem until you get it fixed. Even then, you may only have addressed a sufficient number of the contributing factors involved.

    Luckily between the AC at full blast, and the windows up I can’t hear much outside. But come fall when I return to driving with the windows down all the time I’m going to be irked to no end.

    I'll be honest I changed mine because my throwout bearing was driving me crazy and whenever I engaged reverse it felt like my clutch would explode. I had a shop install it because my starter died and I didn't have time midweek to do anything. I am irked by the noise but its nowhere near as bad as your video ^^. I can't hear it with the windows up at all. Sometimes it's completely silent as well. I really can't see why there are so many different cases with chatter. Only thing I can think of is alignment (I included the tool, not sure if they used it) and torquing sequence of the flywheel. I can't imagine quality control of the actual items to vary so much.

    Alignment tool wasn't provided or needed for mine (835101). I even called Valeo to confirm.

    I used an alignment tool but it definitely played no role. Everything would have slipped together with ease whether I used it or not.

    I followed all torquing instructions from the kit’s paperwork (8 bolt star pattern, increasing torque in steps, using a quality torque wrench). This was supplemented with the BavAuto videos, which were all consistent in the information provided.

    FWIW - as a data point - my OEM clutch (or maybe it's the gearbox) chatters a little when starting off in 1st. The car has 127,000 miles, and to the best of my knowledge it's the original clutch, so I'm not at all surprised there is some chatter. I'd like to do the SMF flywheel at some point so I'll be following this thread.

    My theory is that the dual mass flywheel's rubber dampens the harmonics of the spinning parts of the engine in the same way the harmonic balancer does on the other end. In addition, it provides the "give" needed when starting out from a stop or shifting hard.
    A sprung hub clutch with a single mass flywheel will provide the give needed but will not dampen any harmonics because the springs are metal and in the end, it's still metal to metal contact and any harmonics are transferred to the transmission.
    Why some do and some don't?
    Could be the front harmonic balancer has failed or other anomaly in the engine causing excessive harmonics.

    I'll definitely be sticking with the dual mass flywheel after reading this thread...

    Small update. Installed m3 Motor and transmission mounts. Made everything a bit worse I now hear the chatter when pulling off from a stop just like some others have mentioned. C'est la vie

    I began with the tear-down and install of this kit. Will report back with my results.

    I would always use an alignment tool. I've tried to install transmissions without it and it was bitch. Also, there is a good chance of damaging the pilot bearing if it's not lined up correctly
